Carlsbad Caverns

I have strong and positive memories of the Caverns from my 1967 vacation with my parents and youngest sister.  Rhonda was thrilled with it.  When I visited in 1967, they used a variety of colored spotlights on the features, and they were beautiful.  Now they are entirely white lights.  I asked a ranger about this.  She explained the heat was causing mold to develop, so they are now entirely LEDs.  Still awesome.

  1. sort of an odd justification. as i recall, at least red, orange, yellow, and green LEDs were available before white. (white LEDs actually being some combination of blue + others, and maybe even non-LED stuff.)
